SCALE at Scale: Cosmological applications of small-scale CMB lensing

Autor: Chan, Victor C., Hložek, Renée, Meyers, Joel, van Engelen, Alexander

The Small-Correlated-Against-Large Estimator (SCALE) for small-scale lensing of the cosmic microwave background (CMB) provides a novel method for measuring the amplitude of CMB lensing power without the need for reconstruction of the lensing field. I

High-redshift, small-scale tests of ultralight axion dark matter using Hubble and Webb galaxy UV luminosities

Autor: Winch, Harrison, Rogers, Keir K., Hložek, Renée, Marsh, David J. E.

We calculate the abundance of UV-bright galaxies in the presence of ultralight axion (ULA) dark matter (DM), finding that axions suppress their formation with a non-trivial dependence on redshift and luminosity. We set limits on axion DM using both P

Cosmological simulations of mixed ultralight dark matter

Autor: Laguë, Alex, Schwabe, Bodo, Hložek, Renée, Marsh, David J. E., Rogers, Keir K.

The era of precision cosmology allows us to test the composition of the dark matter. Mixed ultralight or fuzzy dark matter (FDM) is a cosmological model with dark matter composed of a combination of particles of mass $m\leq 10^{-20}\;\mathrm{eV}$, wi
